Abstract
This journal issue opens with Bruno Langlet and Jean-François Rosecchi’s French translation of the second and third sections of Bertrand Russell’s article “Meinong’s theory of complexes and assumptions (1904).” Russell, a defender of logical realism, provides an analysis of Meinong’s thoughts at the turn of the century - thoughts that ultimately lead to Object Theory. Russell aknowledges the deep agreement between himself and Meinong, at this period in time, concerning several principles, arguments and theses. In these sections of his article, Russell exposes and analyses Meinong’s theory of assumptions (1902), then proceeds to an analysis of the object of mental acts.
